Show HN: We built open OpenRouter that turns usage into a better model

Experiential

Experiential is an open source gateway and router for agent workflows:

Use hosted, BYOK, and local models through one OpenAI-compatible API. Control which users and agents can use which models, for which use cases, and how much they can spend. Turn production traffic into a custom router or model optimized for quality, speed, and cost.

Getting Started

Start a local OpenAI-compatible gateway. On first run, the setup wizard uses the shared provider, model, and reasoning-effort selectors, persists every selected provider connection, then shows defaults for the public alias, identity, and $50.00 command budget before printing a one-time key:

pip install experiential exp

Choose a public alias such as opus-5 , capture the issued key, and send a request:

export EXP_GATEWAY_KEY=... curl http://127.0.0.1:8000/v1/chat/completions \ -H " Authorization: Bearer $EXP_GATEWAY_KEY " \ -H ' Content-Type: application/json ' \ -d ' {"model":"opus-5","messages":[{"role":"user","content":"Help me"}]} '

Setup / get started with the hosted gateway
